| I expect that Lego has designed the RCX so that hooking up an output port to an input port directly will not damage it. Kids will probably do that just for fun sooner or later. Hooking up a motor to an input port should therefore be safe, too, as it (...) (25 years ago, 9-Jun-99, to lugnet.robotics)
